Cannon Fire Along the Border

Drug smugglers in Mexicali took aim at the USA, firing packets of marijuana over the border with a cannon. The improvised artillery, made from plastic pipe and an old metal tank, used compressed air to fire packets weighing up to 30 pounds into California.

How far can a cannabis cannon shoot? About 700 meters, estimates Dr. Rhett Allain of Southeastern Louisiana University, over 7 1/2 football fields. Dr. Allain points out that a good ol’ American Punkin Chunker could probably triple that. Even so, the pneumatic cannon is a giant advance over another drug smuggling technology, the marijuana catapult.
